[SOLVED] External hard drive not mounting

NTH · 07-24-2013, 06:19 PM

Hi,
I want to simply mount a 2TB HPFS/NTFS. I havve created a mount point and here is what I've tried unsuccessfully:

sudo mount -t ntfs-3g /dev/sdc1 /media/external

I am using ubuntu and have ntfs-3g. Sudo fdisk -l and blkid show the device ID and partition but it does not show up in mount.
Thanks for the help

Which release of whatever distribution of Linux are you using and why not post the output of those commands so we can see that?

can you give the result of /proc/partitions result?

this seems like mounted anyway try with mount -a and /proc/mounts see if sdc1 will show there?

On my system, I get output on all partitions of attached drives with the 'blkid' command. The mount command itself only shows partitions mounted with an entry in /etc/fstab.

Since you indicate you have Ubuntu installed and want to upgrade Ubuntu and all the filesystems on your first two drives are Linux filesystems, it would be a good idea to use gparted to create partitions on the externa and format them to the appropriate filesystems, ext2, ext3, ext4 before trying to save your data. I'm not sure why the mount command you are using for the ntfs partition doesn't work.

Here is the /proc/partitions:

major minor #blocks name

8 0 976762584 sda
8 1 96256 sda1
8 2 19530752 sda2

8 17 976762583 sdb1
8 32 1953481728 sdc
8 33 1953480704 sdc1

And this is /proc/mounts:

I can see sdc1 in /proc/partitions but not in /proc/mounts. I added these lines in /etc/fstab:
#Entry for /dev/sdc1 :
UUID=F474B7AA74B76DCC /media/external ntfs defaults 0 2

and then used mount -a but /dev/sdc1 doesn't get mounted.

consider changing the filesystem

I do not get any error when I use mount -t .... command but I cannot see the partition /dev/sdc1 in the list of mounted partitions in /proc/mounts. I noticed that it is not probably mounted when I started backing up to the mount point /media/external using sbackup and my root drive filled up.

michaelk · 07-25-2013, 01:54 PM

Look at the output of the dmesg command. There could be some error messages.
Hmm... no errors messages, nothing but a new command line prompt?

lleb · 07-25-2013, 02:09 PM

after running your mount command run a df -Th and post the output of both the mount and the df -Th in a single block of code. thank you.

There is no error message and it goes to a new command line.
Here is the tail of the dmesg output which is relevant to the external hard drive:

sorry this is what i meant. please use code flags. much easier to read:

Code:

[root@centos ~]# mount -t vfat /dev/sdc1 /mnt/usb
[root@centos ~]# df -Th
Filesystem    Type    Size  Used Avail Use% Mounted on
/dev/mapper/vg_centos-lv_root
              ext4     50G  4.7G   43G  11% /
tmpfs        tmpfs    939M     0  939M   0% /dev/shm
/dev/sda1     ext4    485M  144M  317M  32% /boot
/dev/mapper/vg_centos-lv_home

/dev/sdc1     vfat     16G 1009M   15G   7% /mnt/usb

so mount your device via your command, then run the df -Th command. you can clearly see that i mounted a vfat (FAT32) type usb flash drive to /mnt/usb you can see its size, type, and amount of space free.
